`To alt whomz't may concern;

' Be it known that I, FREDERIC W. Winsu-v BROOK, of Brooklyn, in the county of Kings aiid'State of New York, have invented `cer- Improvements in Gas-Regulators, of which the following is a full, clear, and exact` ceiver and. the beer-keg. Y Fig. 2 is a vertical sectional viewof one form of the gas-regu-` lator. F1`g.3 1s a vertical sectional View ofk 'the gas-regulator illustrated in Fig. 1 re- `-versed.,l "i

Theguaturev of myinyention consists in securing, in a suitable shellor casing provided with air-openings and. anf'indu'ction andy eduction pipe, an elastic diaphragm, and to which isf-secured, by suitable gearing, a valve arranged `to automatically 'open and close an Y, opening or Orice in the supply-pipe' through which the gasis supplied to the ihterior chamber of theshell. s y The valve must beso arranged in connection with its seat as to act directly thrugh y theadverse pressure on the opposite sides of the diaphragm, as `the respective degrees of pressure alternately predominate, and en-. tirely irrespective of the. pressure of gas in --the gas-containing vessel or supply-vessel; and to accomplishl this purposeaud herein lies the very essence ot' the inventionthe openin g in the valve=seat or the'discharge-orilice of the supply-pipe must, be so exceedingly small that, While it Will readilysupply the gas when Voccasion requires, or when the. valve,

l through pressure, is opened, at the same time lto render it impossible, when said openin g is closed bythe valve, through the pressure of gas actingon the diaphragm, that the pressure of the gas in the gas-containing-vessel shall in any manner have the effect toopen saidvalve. f y. The constructionand operation of my n1- v,vention are as follows:

` Ais :the caseor shell, and ,while the body of the same iS represented in the accompanying drawing` to be ofl a cylindrical A.ifo-'rumyet,

fif desired, it may` be constructed ot`any other form, and out Ot' any suitable` material., The

body of the shell A-is provided with arched or dome-shapedend pieces B B1, rand which are screwed or otherwise attached to the cylluder.y The ,end piece Bl is formed in one piece, and without any openings, and is the domeor convex base, according to vthe posiion in 'which the apparatus' is used, of the section of the cylinder'which incloses the ygas compartment or chamber A1; The end piece B is formed with a cylindrically-inclosed opelr.

ing or throat B2, through which passesiiiul Works the valve-rod, and is provided, as as its throat B2, with'iitimerous small orifices' or openings, b b. `Through this throat B2 and 'Y the numerous smaller openin gs suiiicient air to secure the desired atmospheric pressure to open the valve, when occasion requires,is readily admitted. or convex base, as the case may be, ofthe airchamber A2. The body of the shell A is provided with two O1` enings,a a, and to which are secured the lateral pipes C G1; The' 'first of these pipes enters the `gas-ehamber A1 of the shell A, andis provided with a small Open ing, c, and iu which enters and registers the opening of the valve-seat C2. This pipe C supplies the carbonio-acid gas from the generator or receiver X, and is connected immediately therewith, asclearl y shown in Fig.1. This generator or receiver Xis 4provided with a stopl cock, av, by meansf-Of which the supply ofgas can be cut oft entirely, when occasion requires.

The pipe `O1 is a coupling or supply-connection pipe, and leads directly and is attached to the barrel or keg y, inconnection with which the apparatus is to be temporarily used. Dis the diaphragm, and is constructedof any suitable elastic material, and is secured between the body of the shell A audits end pieeeB.` This diaphragm D, ,when secured inthe case or shell, divides'the interior 'ot' the.h same, `as it were, into two compartments, Viz., a gas-charm' This end Ipiece B forms the dome 2 lssncrr valve-rod F, The parallel arms ot' thisyoke Ework on the opposite sides of the pipe C, and hold the valve-stem iu position to'insure its'properl action, in connection with its seat plzand the small openingc, i'n the gas-supply. pipe C, and .through which the-carboniol gas passes tol the chamber A1. The valve-rod is provided with a screw-thread, and passes through a small central opening, d, in the diaphragm D, and is securely connected therewith by screw-nuts or washers f f.

'lhe degree of pressure whichthe diaphragm may resist may be regulated by .means of Weights o, as clearly shown in Fig. 3, and

. which will aid the atmosphere in opening'the valve, and cause a' greater'pressure of gas to overcome the same and close the valve;`and when `the apparatus is used in this-position; that is, as illustrated in Fig. 3-*the Weights o yon the rod F canbe so adj usted or regulated as to charge the beer with carbonio-acid gas toany required pressure, While the apparatus, When vused in the position shown in Figs. 1 and 2,

is in position to charge the beer with carbonicacidgas without any pressure-' -that is, the

apparatus', 'when inthis position, will just ad- 'mit suiiicient gas to Iillthe vacuum in the barrel or keg' occasioned by the drawing ofi' of the liquor in the vessel, and does enter the same so-driven or impelled by any pressure.

' From thetforegoing description the operation lof my apparatus will be readily'understood. -The barrel or, keg, and which is represented in miniature at Y, Fig. 1, containing ale, beer, or any other liquid which it is de- 'signed to charge with carbonic-acidgas, having been tapped andreadyfor use, the pipe or coupling- 01 is connected therewith, and

the pipe G is secured to the vessel X containing'the carbonic-aeid gas. The gas-chamber A1 in the receiver A being empty, no resistr ance is offered to the'action ot' the air, andv consequently, through atmospheric pressure,

.the diaphragm D is readily lifted, and which, carrying the valve-rod F with it through the yoke E', withdraws' the valve from its .seat

the valve-rod F, and, through the yoke E, 1 draws down the stem E, so as to close the' valve, and which, for the time being, eiiectually shuts oli' all further admission of gas,

.have a stale avor.

So soon, however, as any of the liquid is drawn from the barrel or keg, the carbonicacid gas rushes from the chamber A1, through the pipe C1, into the vessel Y, illiu g the space which the liquid just displaced. occupied; but this transferring of the gas from the chamber A1 to the vessel Y necessarily leaves a partial -juction with 'the atmospheric pressure,l lifts the diaphragm', and which opens the valve for the ingress-dimore gas, and the valve remains open' until the pressure or weight of the-gas overcomes the force of the 'atmospheric pressure aud depressies. the diaphragm, which closes the valve; 'and thus it will be seen that carbonio gasis suppliedfto the barrel or keg in connection 'with which the apparatusjs used precisely in the degree in which a vacuum is created therein by the dis; placement of the liquid, and4 practical experience has fully demonstrated the fact that this apparatus so' supplies the .gas that, no matter how slow the process of emptying the barrel, the aleor beer does not becomeat or On the contrary the last glass drawmis just as lively, and has as rich and resh a` taste, and froths precisely the same, as the rst glass drawn.

The operation herein just described has .particular reference to the apparatuswhen used in the position illustrated inFigs. 1- and 2 of the accompanying drawing, and in which the gas passes to the liquid-vessel simply through.

its natural escape by the pipe G1, the gas not being driven or impelled under any pressure.

Therefore, when it is desired to charge the beer or other liquid with a high degree of gas, the apparatus should be reversed and the rod F Weighted, so as to control the pressure of gas which the diaphragm will resist, and which can readily regulated at pleasure.

The operation'of the apparatus when in th position shown in Fig. 3 is in all respects sub'- vstantiall'y similar to that of Figs. land 2,.the simple difference being in Fig. 3the atmosphereis aided by the Weight of the valve-con;l nectionsin keeping the valve open,`aud the gas 'that ,the diadegree ofv the pressure. of phragm will resist before closing the valve-by the application of weights o on 'the rod can be 'regulated at pleasure. 'v f What I claim as new, and'desireto secure by Letters Pat-ent of the United States, is- LA shell or case, A, provided with airopeuings, diaphragm' D, v'alve E, andpipe C,

irrespectiveef the varying degree of pressure which thelgas-supply vessel may containhsub' stantially as described.

case having air-openings and lateral openings for the inlet and egress'of gas, au elastic diaphragm, D, valve-rdd F, yoke E', and valve vacuum in said chamber, which, acting in con- 2. In combination with a suitable shell or E, thelatter being varranged as shown, wherey 'y'.by the discharge-opening c of the inlet-pipe shall be automatically' opened and. closed by 4said. valve thron gh the adverse pressure of the atmosphere and'gas acting on `theelastie diaphragm, substantially as,v described.

In testimony whereof I have signed my i' name ,to this 4specification in the presence of two subscribing witnesses.
